“O sink hernieder, Nacht der Liebe” (“Descend, o night of love”): No one has expressed emotional exuberance and feelings of boundless ecstasy more powerfully than Richard Wagner. In the second act of Tristan und Isolde he created a sound world celebrating the act of love – and was himself shocked by the powerful effect his own music had: “I fear that the opera will be banned,” wrote Wagner to his muse, Mathilde Wesendonck. “Only mediocre performances can save me! Completely good ones will drive people to insanity.” Be forewarned, then, that this concert may induce in you a state of madness! … Daniel Barenboim’s West-Eastern Divan Orchestra is also capable of playing a tremendous diversity of music, as we will hear in the program’s first half, which features new works by the Israeli composer Ayal Adler and the Syrian composer Kareem Roustom. And it’s all in the spirit of Wagner: “Children! Make new things!”
